Dual-lipped edge, The spouts work really well, and its great that theres one on each side, so it doesnt matter whether youre pouring with your left or right hand. The handle is very securely riveted to the pan and long enough to avoid heating excessively while using. Another space-saving feature with this is the hole in the handle, allowing me to hang it on the wall. Inside markings for 150ML and 300ML. They are indelible markings on the inside of the pan for precise liquid measurement. The bottom is perfectly flat and relatively broad, and the tri-ply makes it heavy enough to sit evenly on the heavy grates of the gas range, without tipping, even though its a very small pan. The tri-ply aluminum encapsulated base is also made to assure quick uniform heating over the entire bottom. This is a perfect little pan for making small batches of sauces: making teriyaki sauce, melting butter or cheese, heating milk for coffee, as well as heating sake in Japanese pouring bottles.
